Thanks so much for the replies! Someone always comes up with something I haven't thought of yet!
CJPsMom: Yes, we are doing continuous feeds overnight. We do 360 ml at 65 ml/hr. I am interested in the bolus feeds idea. I think this would help the enzymes work better. At what times are you doing the feeds? I would rather not get up in the middle of the night to do one, but I will try anything!
MaryamsMommy (Karen): His docs don't have any concrete answers or advice. He has struggled with weight gain and GI problems his entire life, but he is "healthy" otherwise, which is probably why they are not too aggressive. His BMI just got down to 50%, which is the freak out point at our clinic, so now they think we should do a bronchoscopy and endoscopy, but neither are scheduled.
I'm not really sure what a "motility issue" is. He has chronic constipation which we treat with daily Miralax and increase as needed. He also gets diarrhea. He has a lot of symptoms of "short gut", but his GI doc says he has too much intestine left to be considered short gut. He does have SIBO (small intestine bacterial overgrowth), which is what I think is eating up his calories. He also had his gall bladder removed shortly after birth, so his digestion is even worse than the "typical" CF kid.
We are running the pump at 65 ml/hr. We have experimented with different rates, nothing seems to make any difference. We are now using Pediasure Peptide 1.5. I tried to get Peptamen Junior 1.5, but our clinic seems determined to use Abbott products (probably because of the support they give to the CFF).
I looked up GJ tubes and it didn't seem like it would help in his situation, but I will run it by GI. Is your daughter using TPN specifically for weight gain? I know about the risks to the liver, our son had liver problems at birth. It is unknown if it was due to TPN or CF. I did read about a new TPN product, Omegaven, that has been shown to reduce the stress on the liver.
Mom2Brinly: Yes, we will be trying the new enzyme, Pertzye, soon. I have never vented him. I will try that. Thank you for mentioning it...I never would have thought of that.
